Can Apistogramma uaupesi and Blue Pearl Shrimp Live Together?
Apistogramma uaupesi and Blue Pearl Shrimp are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Apistogramma uaupesi and Blue Pearl Shrimp?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.
Behaviour & Temperament
Apistogramma uaupesi is a moderately assertive species (5/10), while Blue Pearl Shrimp is peaceful (0/10). This notable difference means Apistogramma uaupesi may occasionally assert dominance over Blue Pearl Shrimp.
Apistogramma uaupesi and Blue Pearl Shrimp both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
The pH requirements of Apistogramma uaupesi (4–6) and Blue Pearl Shrimp (6.5–8) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Apistogramma uaupesi needs 0–5 dGH while Blue Pearl Shrimp requires 6–15 dGH.
Tank Setup
To house Apistogramma uaupesi and Blue Pearl Shrimp together, plan for an aquarium of at least 60 litres with a minimum length of 60 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.
Specific environmental needs for this combination include: Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Established Algae (Otocinclus). Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
Why This Pairing Usually Fails in Practice
Apistogramma uaupesi and Blue Pearl Shrimp are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Diet & Feeding
Feeding time deserves special attention with this pairing. Apistogramma uaupesi is a known shrimp eater and may prey on small invertebrates or nano fish like Blue Pearl Shrimp.
Frequently Asked Questions
Can Apistogramma uaupesi and Blue Pearl Shrimp live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma uaupesi and Blue Pearl Shrimp need?
A minimum of 60 litres (tank length at least 60 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Apistogramma uaupesi and Blue Pearl Shrimp together?
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Apistogramma uaupesi or Blue Pearl Shrimp aggressive?
Apistogramma uaupesi is moderately assertive (5/10) and Blue Pearl Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Apistogramma uaupesi and Blue Pearl Shrimp need?
Their pH requirements do not overlap. Apistogramma uaupesi prefers 4–6, while Blue Pearl Shrimp needs 6.5–8. This makes them incompatible in the same water chemistry.
How do I manage Apistogramma uaupesi's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma uaupesi space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
